The point in contention was legitimacy, not competence. The Myanmar Army is unquestionably making things better for themselves, their families and their commercial interests. The CCP is very efficient at expunging non-Han regional cultures, suppressing dissent and the institutionalising the rape of minority women, among other things. In both cases they are only interested in pursuing selfish goals.

Chaotic Evil is selfish anarchy. The Tatmadaw doesn't want anarchy, they want highly regularised, conformant subservience to their rules. If anything they find democracy too chaotic for them to stomach.
